IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 186,088, dated January9, 1877; application filed December 4, 1876.

To all whom it may concern:

Be it known that I, SAMUEL HUBER, of Danville, in the county of Montourand State of Pennsylvania, have invented a new and Improved Plow, ofwhich the following is a specification Figure 1 is a side elevation,showing the land-side. Fig. 2 is a side elevation, showing themold-board and share. Figure 3 is a view looking toward the bottom ofthe plow.

Similar letters of reference indicate correspondin g parts.

Myinvention consists in attaching the share to the plow by means of aprojecting finger or dowel that fits into a corresponding aperture inthe mold-board, and in locking the share by means of a dovetail in thebeam and land-side, the object being to provide a means for fasteningthe shares or points of plows without bolts.

Referring to the drawing, A is the beam of the plow, to which themold-board B is attached by means of bolts in the ordinary Way. 0 is theland-side, which is attached to the plow by means of bolts a a, and isprovided with a lug, b, that fits in a slot, 0, in the shank of theplow. The front end of the land-side has formed upon it a dovetailprojection, 07, that fits into a corresponding recess, 6, in the side ofthe share D. A notch,f, is out in the beam, which, together with theupper side of the dovetail projection 11, forms a dovetail recess, intowhich the part 9 of the share fits. An aperture, h, is made in themold-board at the angle of the recess, in which the back of the sharefits, and a finger or dowel-pin, a,

formed on the share, projects through the said aperture, and securelyholds the share in its position in the recess in the mold-board.

If the point should become loosened by wear or otherwise it may be drawnagainst the beam by placing lagging between the front end of the slot 0and the lug-pin b, and drawing the land-side down against the shank orframe of the plow by means of the bolts a a.

The advantages of this method of fastening the share are obvious. N 0bolts are required, and consequently the surface of the share may besmooth and entire, the usual danger of breaking the share by tighteningthe bolts is obviated, and it is not liable to become accidentallyloosened.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. The plow-share D, having formed upon it the fingeri for engaging with the aperture h, in the mold-board, and a dovetailrecess, 0, and projections g g, for engaging with the beam andland-side, substantially as shown and described.

2. The combination of a share, D, made substantially as described, themold-board B,

.having the aperture 2', the land-side (J, provided with the dovetailprojection d, and lugpin 1), and the beam A, having the recess f andslot 0, substantially as shown and described.
